Eset File Security for Windows issues

I have an issue with running Eset File Security on a VMware hosted 2008 R2 server. It previously wasn't updating anymore after a few days with a "Error allocating memory" error, at this moment it is talking about a General compile error.

Somehow updating doesn't want to work properly. I already reinstalled following a support email, but I can't seem to get a normal functioning anti-virus.

Did somebody else have the same issue(s)? And most important know a way to resolve it?
